Down syndrome is a genetic disorder in which a person is born with an extra copy of chromosome 21. There are three genetic variations that cause Down syndrome: Trisomy 21, Mosaic Trisomy 21 or Translocation Trisomy 21. There are many ways in which theses disorders affect the body. Trisomy 21 occurs when an egg or sperm comes in with an extra copy of chromosome 21, then, once an embryo is formed and starts to develop, the chromosome is replicated in every single cell of the embryo. Trisomy 21 is
Down Syndrome Down's Syndrome, it is one of the most frequently occurring chromosomal abnormalities found in humans effecting people of all ages, races and economic levels. It is a chromosomal anomaly in cell development that results in a person being born with forty-seven chromosomes instead of the normal forty-six chromosomes. People with Down syndrome may have mild to severe learning disabilities and physical symptoms, which include a small skull, extra folds of skin under the eyes, and
Down Syndrome Have you ever been in a situation where you were confronted by a child who has Down Syndrome and were unsure of how to act around that child? I'm sure many of us have experienced the awkwardness that accompanies such a situation. Many people feel guilt or pity for these children, I believe these reactions result from a lack of knowledge about the condition. Which is why I have chosen this topic. Down Syndrome is a condition that cannot be physically passed on from one

chromosomes. The extra chromosome causes Down syndrome. After fertilization; cells start to divide rapidly. Depending on how the cell divides determines what type of Down syndrome the child has. Mosaic Down syndrome is obtained when a cell divides abnormally, creating a string of cells with the extra chromosome. A child with Mosaic Down syndrome has both cells: the normal 46 chromosomes, and the Down syndrome 47 chromosomes. It is believed that babies with Mosaic Down syndrome experience mild symptoms of the
Understanding Down Syndrome Down syndrome is one of the most commonly occurring genetic chromosomal disorder. One in every 800 babies in the United States is born with Down syndrome. It has been estimated that approximately 400,000 people are living with Down syndrome in the United States (Center for Disease Control and Prevention). I have a family member and a friend who have given birth to babies born with Down syndrome. Neither my family member or friend was screen for Down syndrome during pregnancy
individuals experience cognitive delays, but the intellectual disability is usually mild. (Antonarakis SE, 2004). People born with Down syndrome have a variety of birth defects such as heart defects or even digestive abnormalities. (Ackerman, 2012). People with Down syndrome also have an increased risk of developing Alzheimer’s disease. (Di Domenico, 2013). Most cases of Down syndrome are caused by the trisomy of chromosome 21 instead of having the usual pair of chromosome 21. (Hollis 2013). Researchers believe
Down syndrome is a situation in which a person is born with too many copies of the twenty- first DNA segment. Every human being has a total of twenty-three genetic factors, in which about fifty percent are paternal. This disability has three causes which include Trisomy twenty-one, Mosaic Down syndrome, and Translocation Down syndrome with Trisomy twenty-one being the primary. Many people feel Down syndrome is hereditary but this carries a very small percent of proof. Down syndrome does not affect
According to Pennington, Down syndrome is one of the oldest and most common forms of mental retardation. In spite of this, not all people with Down syndrome suffer from mental retardation; yet when it manifest, it is severe in some. Consequently, severe cases could result in delays both mentally and physically. One developmental problem is having a smaller brain size. The smaller brain could cause a lost in short and/or long term memory. Considering the possibility of both parents suffering from
Down syndrome is a chromosomal disease caused by an abnormality dealing with the 21st chromosome. Down syndrome is unique to each individual, and three different kinds can occur. The three different types include Trisomy 21, Translocation, and Mosaic Down syndrome. Not only do these differ, but they all affect the body in different ways. Down syndrome affects appearance, mental cognition, and one’s ability to speak and learn. Down syndrome is caused by an abnormality with the 21st chromosome. It
